BACKGROUND OF THE INVENTION

Traditional prefabricated firing ranges use containers as building blocks to creates a large firing range. Typically, these prefabricated shooting ranges are made from shipping containers that were manufactured to relatively low tolerances. However, individualization and customization often requires modifying each individual container accordingly, which results in increased construction time and costs. Additionally, joining two containers during the construction of a prefabricated firing range, therefore, could result in gaps at the join that could potentially lead to a gap in ballistic containment. To overcome this, previous prefabricated firing ranges would provide an overlapping baffle with the next container. This baffle, however, could create a pinch point reducing linewidth, create space for turbulent airflow, and/or fail to completely remove the gap in ballistic containment for misfired rounds.

Traditional prefabricated firing ranges were separated into separate lanes, where each container includes, for example, two adjacent firing lanes. Container walls were also retained to provide separation between firing lanes form separate containers. Thus, traditional prefabricated firing ranges had separation walls between each lane. However, the separation walls can be limiting, as they may limit visibility of the targets. Separation walls may also limit the capabilities of an instructor to supervise more than a handful of trainees, which can necessitate a small instructor-to-trainee ratio. Moreover, these separation walls can restrict firing exercises and training movements, and can increase cots due to the fact that they are typically fabricated from armored steel.

Traditional prefabricated firing ranges are also limited in capabilities due to roof-mounted HVAC plants. Roof-mounted HVAC plants are installed and commissioned on-site, increasing time and cost while decreasing quality. Because HVAC plants were located on the roof of the prefabricated firing ranges, waterproofing and other concerns are an issue, and any maintenance requires working at height, which increases the risk of injury during maintenance. Moreover, roof-mounted HVAC plants have to be decommissioned and removed to relocate the prefabricated firing range.

Traditional prefabricated firing ranges are further limited in their ability to allow trainees to engage tactically in any direction than toward a down-lane target at a far end of the firing range. Traditional prefabricated firing ranges often use baffles to protect lighting. This may be problematic, however, as such baffles create 1) a pinch point (reducing floor-to-ceiling height), 2) a gap in ballistic containment for misfired rounds, and 3) turbulent airflow.

DETAILED DESCRIPTION OF THE INVENTION

The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

Embodiments of the invention(s) described herein are generally related to a modular firing range. That said, a person of ordinary skill in the art will understand that alternative embodiments may vary from the embodiments discussed herein, and alternative applications may exist.

Prefabricated, modular firing ranges may be used by military, law enforcement, and/or other entities to quickly and easily create a safe, configurable, and cost-effective live-fire firing range for handguns, rifles, and/or other small arms. Such pre-fabricated firing ranges typically include one or more modular containers that are transportable by truck and quickly assembled on-site. These containers (e.g., ISO containers) could be joined to create a firing range with multiple firing lanes, and may be assembled and disassembled to enable the firing range to be effectively transported to any desirable site. For example, each of the containers may define an open interior space that provides space in which a user may move about. By joining the interior spaces of several containers, a scalable firing range may be designed and created.

Embodiments of the invention described herein provided additional features above and beyond traditional pre-fabricated firing ranges to add enhanced functionality. The description herein describes these embodiments, with reference to the attached figures.

Turning now to FIG. 1, one embodiment of a modular firing range 100 in accordance with the present invention is illustrated. The modular firing range 100 is formed from a number of containers 102, such as ISO shipping containers, that have been positioned adjacent and coupled to one another to create an environment that provides targeting and ballistic containment for live fire training exercises. In the illustrated embodiment, the containers 102 may fit into three basic standardized container types: A, B, and C, which may be used to form a firing range three containers 102 wide and three containers 102 long.

For example, the container type A may include end rooms that provide space for control rooms, plant rooms, and/or other areas, such as firing stations. This allows container type A to serve as initial entry rooms and/or areas in which a trainer may be to monitor the activity of trainees as they perform drills within the modular firing range 100. This also allows container type A to serve as a starting point for mobile firing drills and/or a shooting stall for stationary firing drills. Accordingly, container type A may include one or more doors that are used to control access to the firing range 100. Other containers 102 may include doors as well (or alternatively), but in some embodiments it may be advantageous to provide doors and/or other access points in container type A to prevent the possibility of someone entering the modular firing range 100 downstream of a live fire exercise that is underway.

Container type B may include open space that provides space/length for the modular shooting range 100. For example, for stationary shooting drills in which the trainee remains stationary and shoots down range at one or more targets, any number of containers 102 of container type B may be inserted to increase the distance between the shooting stall and the target downrange of the stall to increase the length of the firing range 100. Container type B may include any number of targets positioned along a length of each firing lane. In some embodiments, these targets may include popup, drop down, turning, and/or moving targets (such as paper human targets) that may be triggered to move into an engaged position in which the targets are visible to trainees. In mobile firing drills in which a trainee traverses a length off the firing range 100 and fires at targets when made visible, any number of containers 102 of container type B may be used to provide a proper sized training area. In some embodiments, each container 102 of container type B may define one or more firing lanes of the firing range 100 that each allow space for a trainee to use to perform drills.

Container type C may be configured to serve as the termination point for the modular firing range 100. For example, the containers 102 of container type C may include bullet traps, targets, and/or other features that can be placed at the end of each firing lane of the firing range 100. In such embodiments, one or more bullet traps may be positioned near a far end of the container 102 and may collect any rounds that have been fired toward the end of the container 102.

While discussed with container type A being largely used for staging and monitoring, container type B providing firing lane distance and targets, and container type C providing targets and/or bullet traps, it will be appreciated that the functionality of each container type may be modified to suit the needs of a particular application. For example, various containers may be used for completely different functions and/or functions from one container type may be integrated into another container type and/or removed from one container type and put into another. Mobile firing ranges 100 constructed from the containers 102 may be fully customizable as long as care is taken to maintain a 360° ballistic containment profile around any area in which live fire exercises are performed. Moreover, various equipment, such as shooting stalls, staging areas (which may include desks and/or computers/monitors), cameras, targets, bullet traps, and the like may be preinstalled in the containers 102 prior to shipment and/or may be installed during and/or after assembly of the firing range 100. The latter arrangement enables the firing range 100 to be more fully customizable to meet the needs of a particular training environment.

Each container type may have three different versions, such that containers 102 from nine standardized container types can be utilized to create a prefabricated firing range of any width or length. For example, container type A may include three different versions that have different exterior wall configurations. Container A1 may include a front end wall 104 and a left lateral sidewall 106. This allows container A1 to be positioned at a front corner of the firing range 100. Container A3 may include a front end wall 104 and a right lateral sidewall 108. This allows container A3 to be positioned alongside and opposite container A1 to create a closed end of a firing range 100. In some embodiments, only a container A1 and A3 may be used, allowing a user to construct a firing range 100 that is only two containers 102 wide. In other embodiments, such as that illustrated in FIG. 1, any number of containers A2 may be inserted between a container A1 and a container A3 to expand the width of the firing range 100. Each container A2 may include a front end wall 104, but no lateral side walls 106 or 108. As such, the addition of one or more containers A2 may be used to increase the size of the firing range 100 without adding any interior partitioning walls.

Similarly, container type B may include three different versions with different exterior wall configurations. For example, container B1 may include a left lateral wall 106, but does not include any end walls. Container B3 may include a right lateral wall 108, but also does not include any end walls. This allows container B3 to be positioned alongside and opposite container B1 to create sides (and a main body) of a firing range 100. In some embodiments, only a container B1 and B3 may be used, allowing a user to construct a firing range 100 that is only two containers 102 wide. In other embodiments, such as that illustrated in FIG. 1, any number of containers B2 may be inserted between a container B1 and a container B3 to expand the width of the firing range 100. Each container B2 may include no end walls and no lateral side walls. As such, the addition of one or more containers B2 may be used to increase the size of the firing range 100 without adding any interior partitioning walls.

Container type C may include three different versions that have different exterior wall configurations. Container C1 may include a rear end wall 110 and a left lateral sidewall 106. This allows container C1 to be positioned at a rear corner of the firing range 100. Container C3 may include a rear end wall 110 and a right lateral sidewall 108. This allows container C3 to be positioned alongside and opposite container C1 to create a closed end of a firing range 100. In some embodiments, only a container C1 and C3 may be used, allowing a user to construct a firing range 100 that is only two containers 102 wide. In other embodiments, such as that illustrated in FIG. 1, any number of containers C2 may be inserted between a container C1 and a container C3 to expand the width of the firing range 100. Each container C2 may include a rear end wall 110, but no lateral side walls 106 or 108. As such, the addition of one or more containers C2 may be used to increase the size of the firing range 100 without adding any interior partitioning walls.

The use of such a modular container system creates a scalable modular firing range system that only requires nine different container designs to be fabricated, while allowing any number of configurations with any number of firing lanes available to satisfy the needs of a particular training operation and/or space constraints. Such systems make size adjustments a matter of adding and/or subtracting rows and/or columns of containers 102. For example, reducing the width of the firing range is as simple removing a row of containers (e.g., A2-C2), while reducing the length of the firing range is a matter of removing a column of containers (e.g., B1-B3). On the other hand, additional rows (A2-C2) and/or columns (B1-B3) can be added to create a firing range having any width or length.

While discussed as having three main container categories, it will be appreciated that other container categories (or fewer) may be utilized to fit the needs of a particular application. The number of container categories may have an effect on the total number of variations of containers necessary to craft the various configurations of firing ranges, as adding to the number of primary container categories (A, B, C, etc.) may require larger numbers of container types to be produced. When selecting container configurations, any combination may be connected to provide a continuous outer wall that serves as a ballistic containment perimeter for the live firing exercises.

While not discussed as having any interior walls, firing range 100 may include interior walls in some embodiments. For example, dividing walls, partitions, stalls, and/or other obstructions may be positioned in the modular firing range 100. These obstructions may extend along all or part of a single container 102 and/or multiple containers 102. In some embodiments, the obstructions may extend fully from a floor to ceiling, while some obstructions extend partially upward from the floor. It will be appreciated that some of these obstructions may be formed from exterior walls of the containers 102. For example, some or all containers 102 may have both right and left lateral sidewalls 106, 108 such that some of the lateral sidewalls are positioned in an interior of the firing range 100 and serve to divide the firing range 100. In other embodiments, the only lateral sidewalls of each container 102 are those described and illustrated with respect to FIG. 1. Such embodiments enable firing ranges 100 having open floor plans to be constructed as discussed in relation to FIG. 9A. The obstructions may be positioned interiorly of container sidewalls in some embodiments. These obstructions may be constructed as part of the containers 102 themselves and/or may be affixed to the interior the containers 102/firing range 100 during assembly of the firing range 100.

FIG. 2 demonstrates an isometric view of a portion of one firing range 100 arrangement constructed using containers 102. For example, two containers 102 of each of container types A, B, and C are shown here to produce a firing range 100. As shown here, the containers 102 of container type A include staging areas 112 and shooting stalls 114. The containers 102 of container type B include firing lanes 116, and the containers 102 of container type C include bullet traps 118 that are designed to receive and retain any ballistic shells that are fired toward a distal end of the firing range 100.

Such containers can be used to create an entirely open range by rotating the containers 90 degrees, such as shown in FIG. 3. Here, rotated containers 302 allow for the creation of an entirely unobstructed shooting for multiple parallel shooting lanes (up to 9, according to some embodiments, although other embodiments may have more or fewer shooting lanes).

Containers 302 may be modular, in a manner similar to the modular containers 102 illustrated in FIGS. 1 and 2 above. That is, two sets of one or two containers D1 and D3 may be used at each end and there may be a modular type of container D2 used between these two sets of containers to comprise the firing lanes of the firing range, where any number of these modular containers D2 may be used, based on desired length of the firing range 300. Such a modular container may therefore be similar to the modular container B2 shown in FIG. 1 above.

As shown, three versions of containers 302 may be utilized to construct a firing range 300 of any length when positioned side by side along the longitudinal side (with the longest sides of each container 302 being used to define the width of the firing range 300), rather than the lateral side as done in firing range 100. For example, a container D1 may be utilized on a first end of the firing range 300 and may include a left lateral wall 306 (formed by an end of the container 302), a front end wall 304 (formed by a side of the container 302), and a right lateral wall 308 (formed by a second end of the container 302). At an opposite end, the firing range 300 may include a container D3, which may include a left lateral wall 306 (formed by an end of the container 302), a rear end wall 310 (formed by a side of the container 302), and a right lateral wall 308 (formed by a second end of the container 302). Containers D1 and D3 may be positioned on opposite ends of the firing range 300 to provide ballistic containment on either end of the firing range 300. To increase the length of the firing range 300, any number of containers D2 may be positioned between containers D1 and D3. Containers D2 may include a left lateral wall 306 (formed by an end of the container 302) a right lateral wall 308 (formed by a second end of the container 302), but do not include any end walls. Using a three container arrangement as illustrated here allows for any length of firing range 300 to be constructed using three container types, while providing a significantly wide firing range 300 by taking advantage of the longitudinal side by side arrangement of the containers 302.

It will be appreciated that in some embodiments, only two container types may be necessary, as container type D1 may be rotated 180° to form a container of type D3. This is possible in embodiments where HVAC fittings for supply and extraction lines are uniform. Additional concerns with a two container embodiment are the presence of doors and/or other access points at two ends of the firing range 300. For example, if three containers 302 are used, only D1 may include access points, which may prevent users from entering the firing range 300 downstream of an active live fire exercise. If only two container types are utilized, then both ends of the firing range 300 may include access points. In such instances, special care may need to be taken to ensure that the access points downstream of any active exercises are securely locked to prevent accidental entry.

FIG. 4 demonstrates one embodiment of just one arrangement of a firing range 400 formed using three container types such as described in relation to FIG. 3. For example, firing range 400 includes a container 402 of type D1 that defines an entryway 404 to a number of shooting stalls 406 and firing lanes 408 defined by containers 402 of type D2. Bullet traps 410 are positioned at a far end of the firing range 400 in a container 402 of type D2 and a container 402 of type D3 (although in some embodiments only a container 402 of type D3 may include bullet traps 410). In the illustrated embodiment, additional containers 402 are used for additional purposes and may not be necessary in all applications. For example, an HVAC supply container 412 and an HVAC extraction container 414 are provided at either end of the firing range 400 to provide temperature regulation and to control airflow within the firing range 400 as discussed in greater detail below. A control room container 416 is provided near the container 402 of type D1, and a number of storage containers 418 are provided along a side of the firing range 400. While shown here with some of the additional containers being of different container types, it will be appreciated that any of these additional containers may be omitted and/or designed to match an exciting container type (such as type D1 and/or D3) to meet the needs of the particular training application and space requirements while still minimizing the number of different container types that need to be constructed to enable the production of modular firing ranges. It will be further appreciated that the above embodiment is only illustrative in nature and any number of permutations of containers of types D1, D2, and/or D3 may be connected to one another to form firing ranges having desired characteristics.

Embodiments of the invention may optionally include sidewall “pods” that provide an additional space, adjacent to a firing lane, to allow additional engagement by a trainee in a lateral direction relative to the firing range. For example, as shown in FIG. 5, one embodiment of a firing range 500 that includes sidewall pods 504 is shown. Here, firing range 500 is formed in a manner similar to that described in relation to FIG. 1. For example, containers 502 similar to types A, B, and C are coupled end to end (rather than side by side as done in FIG. 3) to form a firing range 500 having an entry/staging area 506, range area 508, and bullet trap area 510. Firing range 500 also includes an HVAC supply container 512 and HVAC extraction container 514 similar to those described in greater detail below. In the present embodiment, the sidewall pods 504 are positioned alongside the range area 508 and project outward from the rest of the outer perimeter of the firing range 500. The sidewall pods 504 in the present embodiment have a wall structure similar to that of container type D3 described above, and utilize two end walls 516 and one lateral side wall 518 to expand the interior of the firing range 500 while maintaining ballistic containment in 360°. While shown here as full containers of the D3 wall configuration, it will be appreciated that other sidewall pod 504 designs, including partial containers, containers in other orientations, and/or multiple containers having the same or different wall structures may be used to construct each sidewall pod 504. For example, a sidewall pod 504 may be formed from several containers 502, such as a sidewall pod 504 formed from a container of type A1 or C1, a container of type A3 or C3, and/or any number (including zero) containers of type B1 or B3, to form an elongate sidewall pod 504. Any combination of containers, sizes, shapes, and/or orientations of containers 502 may be utilized to construct a sidewall pod 504 of a desired size and shape as long as ballistic containment in all directions is maintained.

The sidewall pods 504 may provide additional space for equipment storage/placement within firing range 500. In some embodiments, the equipment may include targets and/or bullet traps. In such embodiments, the sidewall pods 504 provide the ability for training engagement not only down-lane of each firing lane, but also provide lateral engagement techniques that allow trainees to practice firing at lateral targets as well as down-lane targets. This can provide close quarter engagement practice in combination or in alternative to the long distance engagement normally provided by the more elongate firing lanes, as arrangements such as the one illustrated provide target positions that must be relatively close to the trainee. Such arrangements allow for targets to be provided both downstream or laterally relative to a trainee (either simultaneously, or selectively based on the needs of a particular training drill) such that training exercises may involve distance training, proximity training, or both and training exercises may be conducted that involve trainees being forced to switch between distance training and proximity training to locate and engage with the relevant target, which may show up in any direction downstream and/or with respect to the trainee's position within the firing range 500.

As hinted at above, oftentimes modular firing ranges include HVAC systems that provide air circulation, as well as temperature control (heat, air conditioning, humidity control, etc.) to the modular firing ranges. Conventionally, such HVAC systems were mounted to the roof of the modular firing ranges as shown in FIG. 6. For example, an HVAC supply system 602 was mounted at a proximal end of roof of a firing range 600, while an HVAC extraction system 604 was mounted atop a distal end of the firing range 600. Such placement led to several problems, as the height of the HVAC systems required maintenance personnel to climb atop the firing range 600 and service the HVAC systems from an elevated height, which could lead to unsafe working conditions due to the risk of falling. Additionally, roof-mounted HVAC systems such as shown in FIG. 6 require HVAC connections to be made through the roof of the firing range 600. Such connections, while typically sealed, may still run into water leakage problems, especially as gaskets fail, due to the orientation of the connections. Specifically, the connections require upward facing openings to be made in the roof of the containers making up the firing range 600, which may be particularly susceptible to the ingress of standing and/or falling water. These roof-mounted systems also must be decommissioned and removed for storage, and required greater container roof strengths given the weight of the systems and the need to additionally support maintenance personnel who must service the HVAC system.

To provide a simpler, safer maintenance process, as well as to reduce the issue of weatherproofing, embodiments of the modular firing ranges described herein may include HVAC supply and extraction units that are located on the side of the modular containers of the firing range, rather than on the roof. Not only does this alleviate waterproofing and maintenance issues that arise for roof-mounted HVAC systems, but such designs also allow an HVAC plant to be factory installed and commissioned within containers, which are then attached to the modular containers of the prefabricated firing range. Accordingly, these HVAC containers can have modularity similar to the modularity of the containers of the prefabricated firing range. Additionally, such solutions may reduce construction/installation costs and may isolate sound breakout from the HVAC plant, as the HVAC systems themselves are housed within modular containers instead of being mounted to an exterior of the modular firing range. As illustrated in FIG. 7, a modular firing range 700 is constructed having a main firing range body 702 that provides 360° of ballistic containment and which may be constructed according to any design and structure principles disclosed herein. For example, the firing range body 702 may be constructed in a manner similar to that described in relation to FIG. 1 in which containers selected from container types A, B, and/or C are coupled together to form a modular firing range having a staging area, firing range/lane area, and/or target/bullet trap area. In other embodiments, the firing range body 702 may be constructed from containers of container types D1-D3. In some embodiments, firing range body 702 may include modular sidewall pods and/or storage containers.

As illustrated, firing range body 702 is coupled to an HVAC supply container 704 at a proximal side of the firing range body 702. HVAC supply container 704 is coupled with the firing range body 702 using one or more supply ducts 706. These ducts 706 may be installed at the factory and/or may be installed on-site in the field, such as by inserting the ductwork through openings defined in the containers that make up the firing range body 702 and the HVAC supply container 704. These openings and/or the ducts 706 may be sealed, such as using gaskets, to prevent the ingress of water or debris into the HVAC system that could otherwise be passed into the firing range body 702. Oftentimes, the ducts 706 may be coupled with one another and/or the HVAC container 704 and/or the firing range body 702 using fasteners, clamps, an/or other securement mechanisms. For example, fasteners may be inserted through a flanged connection and tightened to couple the various duct components together to create a fluid pathway for air from the HVAC supply system.

HVAC supply container 704 includes any number of HVAC units 708, such as heating units, air conditioning units, humidifiers, dehumidifiers, filtration units, and the like. Air may be drawn into the HVAC units 708 via one or more fluid ports 710 defined in an exterior of the HVAC supply container 704. The number and type of HVAC units 708 may be determined based on the needs of a particular training application, as well as the location, current weather/climate and the like. For example, in the summer, the HVAC units 708 may include air conditioning units to counteract the heat, while in the winter, HVAC units 708 may include heating units. In some embodiments, HVAC units 708 may be selected to simulate a particular set of training conditions. For example, if a set of trainees is training to a mission in a warm, humid climate, the HVAC units 708 may include heating units and humidifiers that can increase the temperature and humidity levels within the firing range. Similarly, if the mission is in a cold dry climate, the HVAC units 708 may include air conditioning (and/or refrigeration) units and/or dehumidifiers to simulate mission conditions.

Oftentimes, the HVAC units 708 may be installed into the HVAC supply container 704 at the factory, requiring only the HVAC supply container 704 be hooked up to the firing range body 702 using the ducts 706 during installation. In such embodiments, each HVAC supply container 704 may be manufactured with the same HVAC units 708 and/or each HVAC supply container 704 may be specially ordered with a particular set of HVAC units 708 to meet the needs of particular application. As just one example, in embodiments where all HVAC supply containers 704 include the same preselected set of HVAC units 708, one or more of each type of available HVAC units 708 may be included.

Also coupled with the firing range body 702 is an HVAC extraction container 712 at a distal side of the firing range body 702. HVAC extraction container 712 is configured to provide a ventilation system to the firing range 700 to allow for fresh air to be pumped throughout the firing range body 702. In some embodiments, one or more fans (not shown) may be used to draw air out from the firing range body 702, which may be expelled through one or more ventilation ports 716 defined by an exterior of the HVAC extraction container 712. HVAC extraction container 712 is coupled with the firing range body 702 using one or more venting ducts 714. These ducts 714 may be installed at the factory and/or may be installed on-site in the field, such as by inserting the ductwork through openings defined in the containers that make up the firing range body 702 and the HVAC extraction container 712. These openings and/or the ducts 714 may be sealed, such as using gaskets, to prevent the ingress of water or debris into the HVAC system that could otherwise be passed into the firing range body 702. Oftentimes, the ducts 714 may be coupled with one another and/or the HVAC extraction container 712 and/or the firing range body 702 using fasteners, clamps, an/or other securement mechanisms. For example, fasteners may be inserted through a flanged connection and tightened to couple the various duct components together to create a fluid pathway for air from the HVAC extraction system.

While shown here with one HVAC supply container 704 and one HVAC extraction container 712, it will be appreciated that any number of supply and/or extraction containers may be utilized in a particular application. Moreover, the size of each container may be adjusted to meet the demands of the application. For example, larger firing ranges 700 may utilize larger HVAC containers such that a greater number of HVAC units 708 and/or connections may be provided to increase airflow effects. In other embodiments, smaller, specialized HVAC containers may be utilized to achieve desired climate effects. For example, a training organization may keep on hand a variety of different HVAC containers for different purposes, such as a refrigeration container that includes units to cool the temperature of a firing range, while a humidity and/or heating container may be hooked up to a firing range to simulate a hot, humid environment. It will be appreciated that any number of combinations of sizes, numbers, and/or types of HVAC containers may be utilized.

Additionally, while shown with the HVAC containers positioned with their sides by an end of the firing range body 702 to minimize the footprint of the firing range 700 and to provide more area for ductwork connections, in some embodiments the HVAC containers may be positioned end to end with the firing range body 702. The placement of the HVAC containers may also vary. Furthermore, in some embodiments, the HVAC containers may be stacked atop the containers that make up the modular firing range. In such embodiments, the ductwork is still configured to connect the HVAC containers to the modular firing range containers on horizontally facing surfaces to aid in weatherproofing.

While placing the ductwork at opposite ends of the firing range body 702 may be useful to minimize irregular airflow or cross-lane airflow, it will be appreciated that the HVAC containers and/or the ductwork connections may be attached with the firing range body 702 at different locations that are not at the ends of the firing range body 702. In some embodiments, ductwork may be elongated and/or bent to allow for placement of the HVAC containers to be along the lateral sides of the firing range body 702 while still connecting the airflow ducts at the ends of the container bodies. While not shown, the containers making up the firing range body 702 may also include interior ductwork that may allow air to and from the HVAC system to be directed to desired locations and in desired directions within the firing range body 702, which may be used to control airflow conditions during firing exercises and/or may allow lateral (rather than end) duct connections of the HVAC systems to have end to end airflow within the firing range body.

FIGS. 8A and 8B illustrate one arrangement of a modular firing range 800 designed in accordance with the present invention. Firing range 800 includes a firing range body 802 that includes an arrangement of modular containers (either from A1-C3 or from D1-D3) that include a staging/control/supervision area 804, a firing range area 806 having a number of firing lanes 808 and a number of targets 810 arranged within the firing range area 806. A number of bullet traps 812 may be provided at a distal end of the firing range body 802. Here, an HVAC supply container 814 is positioned at a proximate end of the firing range body 802 and an HVAC extraction container 816 is positioned at a distal end of the firing range body 802. It will be appreciated that other arrangements of firing range 800 are possible, and that more or less modular containers may be used to create the firing range 800. In addition, different containers, such as sidewall pods may be included to further enhance/customize the firing range 800 for a particular application.

Conventional modular firing ranges that are constructed from ISO shipping containers include separation walls between each container that are formed from the outer (side and/or end) walls of the container itself. In some embodiments, such as those illustrated in the drawings herein, the modular containers of the modular firing plan are modified to accommodate an open floor plan. To do this, some or all of the separation walls may be removed and replaced with a support structure that ties into the existing containers and provides structural strength and stability once one or more sidewalls are removed. The open floor plan allows trainees to move laterally within the firing range, and also provides a greater field of vision for instructors, which leads to increased safety. Additionally, the removal of sidewalls may reduce the quantity of armored steel needed to produce a safe firing range, as there are no separation walls that need to be reinforced.

A support structure 900 that is used to support the roof 902 of a container 904 when a separation wall is removed is illustrated in FIGS. 9A and 9B. Support structure 900 includes a first column 906 that is positioned at (or near) a first corner of the container 904 and extends between a top panel (roof/ceiling) of the container 904 and a bottom panel (floor structure) of the container 904. A second column 908 is positioned at (or near) a second corner of the container 904 that is opposite the first along a same edge of the container 904. The second column 908 also extends between a top panel (roof/ceiling) of the container 904 and a bottom panel (floor structure) of the container 904. Each of columns 906 and 908 are typically made of steel and/or other metal alloys and are between about 100 mm and 300 mm in width, oftentimes about 250 mm, although other widths may be utilized. The width and/or thickness of the metal columns 906 and 908 may be selected based on the weights and/or dimensions of the container 904 and/or the weights and/or dimensions of the separation wall being removed. For example, if the separation wall being replaced by support structure 900 is an end wall, the dimensions may be smaller and smaller columns 906 and 908 may be utilized. Similarly, if the separation wall being removed is an elongate sidewall of a large container 904, the columns 906 and 908 may be scaled up in size to accommodate the additional mass that was previously supported by the separation wall.

Columns 906 and 908 are configured to support a beam 910 that extends across the top edge of the container 904. In some embodiments, a single beam 910 may extend entirely (or substantially) across the top edge such that it fully spans the distance between the first column 906 and the second column 908. This is particularly common for the replacement of shorter separation walls, such as end walls, or side walls of smaller containers 904. In embodiments in which the separation wall being replaced is longer, such as for sidewalls of larger containers 904, two or more beams 910 may be used to span the distance between the first column 906 and the second column 908. In such cases, the beams 910 may often be spliced together, such as using end plated, bolted cover plate, fully welded one sided cover plate, and/or fully but welded techniques.

Beam 910 may be coupled to the columns 906 and 908 in any number of manners. For example, as shown in FIG. 9A, an end of beam 910 is rested atop and secured to each of the columns 906 and 908. The ends of beam 910 may be secured to the tops of columns 906 and 908 using bolted and/or welded connections. In some embodiments, these connections may be reinforced using angle cleats and/or other reinforcement mechanisms. In other embodiments, the beam 910 may be secured between the columns 906 and 908, rather than atop the columns 906 and 908. For example, seat-angle connections, web standard beam connections, combined web seat angle connections, end plate connections, and/or other beam connections may be used to secure the beam 910 with the columns 906 and 908.

In some embodiments, one or more additional columns 912 may be included in support structure 900. Column(s) 912 may be positioned at medial positions at regular intervals along a length of the open side of the container 904. As shown here, a single column 912 is positioned directly in between the columns 906 and 906 and supports a medial portion of the beam 910. Usage of medial columns 912 may be particularly useful for longer containers 904 and/or for containers that have particularly heavy roof structures, as the column(s) 912 provide additional support for the beam 910 and roof of the container 904. Oftentimes, column(s) 912 may be thinner than columns 906 and 908 and often have widths of between about 80 mm and 150 mm, although other widths may be used to meet the structural needs of a particular application. It will be appreciated that it may be desirable to eliminate the use of medial columns 912 to open up the floor plan of the firing ranges as much as possible. In such embodiments, the width, thicknesses, and/or materials of columns 906 and 908 and/or beam 910 may be selected to create a stronger support structure 900 so as to render medial column(s) 912 unnecessary.

Beam 910 and columns 906, 908, and 912 may be any cross sectional shape. For example, beam 910 and columns 906, 908, and/or 912 may have I-shaped cross sections, rectangular shaped cross sections, circular cross sections, and/or cross sections of other shapes. In some embodiments, beam 910 and columns 906, 908, and/or 912 may include stiffeners and/or other features that increase the strength and rigidity of the particular structure, enabling the support structure 900 to support greater loads. In rectangular beam/column embodiments, it will be appreciate that the height and base dimensions of the cross-sections may be the same (square-shaped) or different. For example, the base and width dimensions for a particular column may be approximately 100 mm×300 mm, although numerous other dimensions are possible based on the needs of the particular application.

It will be appreciated that any number of separation walls of a container 904 may be replaced using support structure 900. For example, a container A1, A3, C1, C3, and/or D2 may have two separation walls (one end and one sidewall for A1, A3, C1, and C3 and two sidewalls for D2) removed and replaced with support structures 900. A container D1 or D3 may have a single sidewall removed and replaced with support structure 900. A container A2, B1, B3, and/or C2 may have three separation walls (both end walls and one sidewall for B1 and B3 and both sidewalls and one end wall for A2 and C2) removed and replaced with support structures 900. Container B2 may have all four walls removed and replaced with support structures 900. Still other combinations of separation wall removal and support structure usage may be contemplated in accordance with the present invention to create any desired design of modular firing range with an open floor plan.

Moreover, in some embodiments, a portion of a single separation wall may be removed and replaced with a support structure 900. For example, half of a sidewall of a container 904 may be removed and replaced with a support structure 900. In such a case, the columns 906 and 908 may be positioned based on the outer bounds of the opening provided by the removal of the portion of the sidewall and one or both of column 906 or 908 may not be positioned in a corner of a container 904. For example, if the half of the removed sidewall portion includes a corner of the sidewall, then one of the columns 906 and 908 will be positioned at or near the corner while the other will be positioned at an opposing end of the opening and will not be at or near a corner of the container 904. If the portion of the removed sidewall is from a medial portion (such as the center) of the sidewall, then both columns 906 and 908 will be spaced apart from the corners of the container 904. Such removal of a portion of a separation wall may be particularly useful, for example, in embodiments where a smaller container is used as a sidewall pod that is positioned adjacent a container 904 that has an outer wall formed from a sidewall of a full size container. In such embodiments, only a portion of the sidewall of container 904 is removed to match the shorter dimension of the small container used for the sidewall pod.

The firing ranges described herein, while often fashioned from ISO shipping containers, may have a more finished interior than standard ISO shipping containers. For example, an armor layer, such as armor plating, may be applied to an interior surface of each shipping container. The armor plating may be applied to any side/end walls, the ceiling, the columns/beams of the support structure, and/or the floor. This armor plating may be formed from AR500 steel and/or other ballistic grade shielding that can serve to constrain ballistic projectiles within the confines of the firing range. Oftentimes, this shielding may be between approximately 5 mm and 15 mm thick, with thicknesses of approximately 10 mm being common, although other thicknesses may be used to meet the needs of a particular application. Additionally, a coating or layer of anti-ricochet material, such as a rubber and/or polyboard material may be applied to the armor plating. This provides several benefits. For example, the anti-ricochet material may prevent ballistic shells from ricocheting off interior surfaces of the firing range where the ricochets could make the shells dangerous to the trainees within the firing range. Additionally, the anti-ricochet material may provide sound insulation that will dampen the sounds produced by the firearms or voices within the firing range, and may also prevent or reduce the effect of echoes and other distracting sounds. Furthermore, such coating may provide the interior of the firing ranges with a more finished appearance that provides a more welcoming training environment than plain shipping containers, which may give off a warehouse aesthetic. Such a finished approach is illustrated in FIG. 10, which demonstrates a firing range 1000 having an open floor plan in which the walls 1002, floors 1004, ceilings 1006, and/or support columns 1008 are wrapped in armor plating, which is then surrounded by a rubber anti-ricochet layer.

As discussed above, the modular containers described herein may be constructed using standard ISO shipping containers, which may be manufactured to low tolerances. For example, 40 foot ISO containers are designed to the dimensions and tolerances shown in Table 1.

TABLE 1 40 Foot ISO Shipping Container Dimensions Dimension Tolerance (mm) Classification (mm) Lower (−) Upper (+) External Length 12192 10 0 Width 2438 5 0 Height 2896 5 0 Internal Length 12032 10 0 Width 2352 5 0 Height 2698 5 0 Door Opening Width 2340 5 0 Height 2585 5 0

Even these small size differences lead to gaps in the ballistic containment when containers of slightly different sizes are complexed together to form a modular firing range. Moreover, such gaps can create areas of turbulent airflow that may affect the trajectories of ballistic projectiles firing in the firing range. Prior art solutions involved the use of steel baffles 1102 that overlap an adjacent container 1100 as shown in FIG. 11. These baffles 1102 would be mounted to an interior of the roof structure 1104 of the containers 1100 and be gradually angled and/or bent slightly downward so that each baffle 1102 may extend beyond the start of the baffle 1102 on an adjacent container 1100. However, using baffles 1102 in this manner creates pinch points (at the downward angled/bent portion) that reduce the interior space (lane width and/or lane height), while also leaving a gap 1106 in ballistic containment between the baffles 1102, which not only provide a path through which misfired live rounds can escape the firing range and may create a space for turbulent air flow.

To provide gapless connections between modular containers to eliminate pinch points and maximizing linewidths, as well as to prevent turbulent flows, embodiments may utilize a cleated connection to couple containers together and to provide full ballistic containment as shown in FIG. 12. For example, FIG. 12 illustrates a cross-section of edges 1202 of two adjacent containers 1200 that are coupled together using a cleated connection. As shown here, each container 1200 includes an outer surface 1204, an armored plating 1206 on an interior of the container 1200, and spacers 1208 (such as rods or channels like hat channels or lipped channels) that separate the armored plating 1206 from a rubber and/or other anti-ricochet layer 1210. However, in embodiments in which the sidewalls may be expected to face more direct shooting, such as sidewall pod embodiments, the anti-ricochet layer 1210 may be affixed directly to the armored plating 1206, such as by using an adhesive to bond the layers together. Armored plating 1206 may be permanently affixed to the walls of container 1200, such as by welding and/or other permanent securement techniques. It will be appreciated that the structure of container 1200 is merely one example of the structural and finishing layers of a container 1200 and that other arrangements of container structures may be contemplated in accordance with the present invention. To seal the gap between armored plating 1206 of the two containers 1200, a separate armored plate 1212 is mounted onto the armored plating 1206 of both of the containers 1200 such that the armored plate 1212 spans and covers the entire gap, thereby providing full ballistic containment between the containers 1200. To secure the armored plate 1212 to the armored plating 1206, removable coupling mechanisms may be used such that the armored plate 1212 may be removed when disassembling the firing range. For example, bolts, rivets, and/or other fasteners may be inserted through the armored plate 1212 and the armored plating 1206 to secure the armored plate 1212 to the armored plating 1206. This process may be done prior to affixing the rubber layer 1210 to the armored plating 1206.

Each container edge 1202 may include one or more cleats 1214 that are positioned along the edge 1202. The cleats 1214 may have a fixed portion 1216 that is secured to the edge 1202 using welds, fasteners, and/or other securement techniques. Each cleat 1214 may also include a securing portion 1218 that is configured to contact the securing portion 1218 of another cleat 1214 when two containers 1200 are aligned and adjacent with one another. Fastening mechanisms 1220 may be used to secure the adjacent cleats 1214 together to secure the containers 1200 in gapless contact with one another. For example, in some embodiments bolts or rivets may be inserted through apertures defined by each securing portion 1218 to lock the two cleats 1214 together. In other embodiments, clamps or other mechanisms may be used to hold the cleats 1214 in engagement with one another.

FIGS. 13 and 13A demonstrate the positioning and usage of cleats 1302 (similar to cleats 1214) to secure two containers 1300 together. Here, a number of cleats 1302 are spaced along the sides and top of the mating edges 1304 of the containers 1300 (although in some embodiments cleats 1302 may only be included on one or two of the sides and/or top) at equal intervals to connect the containers 1300 together in an end to end fashion (although similar arrangements may also be used to mate containers 1300 in a side by side fashion). For example, cleats 1302 may be spaced apart every 1-10 feet from one another, with intervals of every 2-5 feet common, and intervals of every 2.5 feet being more common. Each cleat 1302 may be similar to an angle bracket and may include a fixed portion 1306 and a securing portion 1308. Fixed portion 1306 may be secured in a parallel fashion to the outer surface 1310 of an edge 1304 of container 1300 such that an outer face of the fixed portion 1306 is parallel to and faces/contacts the outer surface 1310 of the container 1300. Fixed portion 1306 may be secured to the outer surface 1310 of the container 1300 using fasteners (such as bolts or rivets) and/or by welding. In some embodiments, such as where ISO containers are not used, cleat 1302 may be formed integrally with the container 1300. In such embodiments, the fixed portion 1306 may be a part of the outer surface 1310 and may or may not project outward from the rest of the outer surface 1310.

Securing portion 1308 may project at a substantially 90° angle from the fixed portion 1306 and may provide a mating surface for two cleats 1302 to be brought into contact with and secured to one another to secure the containers 1300 together. Together the fixed portion 1306 and the secured portion 1308 make up a generally L-shaped cleat 1302. Securing portion 1308 may define a number of apertures that are configured to receive fasteners 1312, such as bolts or rivets, that, when tightened, secure the cleats 1302 together. In some embodiments, rather than (or in addition to) using fasteners inserted through apertures in the securing portion 1308, clamps or other fastening mechanisms may be used to couple the cleats 1302 together.

Oftentimes, cleats 1302 may be between 6 inches and 2 feet in length, and lengths of about 1 foot in length are common. The fixed portion 1306 and/or securing portion may form mating flanges or surfaces that are between about 1 inch and 6 inches in width, with widths of between about 2 and 4 inches being common. It will be appreciated that the size and/or number of cleats 1302 used in a particular application may be based on the strength requirements of a particular connection, as well as the geometry of the edges 1304 of the container 1300.

In some embodiments, the spacing and number of cleats 1302 may be selected to provide the greatest level of flexibility in designing modular firing range arrangements. For example, the spacing and number of cleats 1302 may not only allow for the containers 1300 to be perfectly aligned as illustrated here, but may also allow for some or all of the containers 1300 to be staggered relative to one another. For example, one container 1300 may be mated alongside two different containers, such as to include a sidewall pod that needs to be positioned adjacent and overlapping two containers on one side to provide a particular lateral position for a lateral shooting target that does not perfectly align with one individual container of the main firing range. In such embodiments, it is possible that only a portion of each of the two separation walls of the containers of the main firing range to be removed such that when mated with the one container 1300, the two partial openings provided by removal of the portion of the sidewalls combine to form an opening matching that of the single container 1300 to provide a seamless appearance while still providing 360° of ballistic containment.

Such placement of cleats 1302 may also allow containers 1300 to be positioned at various orientations to one another. For example, some or all of the containers may be placed such that an end of one container is positioned against a sidewall of another container 1300. This enables greater flexibility in firing range arrangement (although it may require additional standard container types to be manufactured and/or modified on site by removing some or all of an existing end or sidewall and replacing it with a support structure such as described in relation to FIG. 9A), as nearly any combination and arrangement of containers 1300 may be combined to form a custom firing range to meets the training needs and/or space restrictions of a particular application.

In embodiments using cleated connections, a container's physical dimensions are measured and a centerline is taken in both directions. Location cleats 1302 are then affixed to the container 1300 prior to shipping. For example, the cleats 1302 may be placed at regular intervals from the location of the centerline of the container 1300, either by centering the first cleat 1302 or by spacing two cleats 1302 equidistant from the centerline. This ensures that when the cleats 1302 are aligned, the containers 1300 will be aligned at their centers and will eliminate any possible gaps in the containers 1300 that result from the manufacturing tolerances of the containers 1300 when slightly misaligned as any differences in size will result in the thickness of the container 1300 creating at least some overlap between adjacent containers 1300, thereby covering up any possible gaps between the containers 1300 caused by normal misalignment. This, in combination with the use of armored plates, such as armored plate 1212, to cover gaps formed between armor plating of the containers 1300 ensures that ballistic containment is maximized and the ability for turbulent airflow is minimized when the containers 1300 are mated.

Once the cleats 1302 are aligned, the containers 1300 may then be complexed together using the cleats 1302 as a “hard stop” to help ensure all containers 1300 are located at the centers. Internal armored steel plates can then be set out from the centerline to create full ballistic containment. It will be understood, however, that particular dimensions, (e.g., length and width) are provided as examples, and alternative embodiments may have different dimensions. Such embodiments can mitigate the manufacturing tolerances of the containers and provide full ballistic containment, increase firing lane width by eliminating the use of baffles, and reduce turbulence in airflow.

Typically, conventional modular firing range solutions provided lighting using angled baffles 1400 to provide armor for ballistic containment, while adding light fixtures 1402 in the gaps provided between the angled baffles 1400 as demonstrated in FIG. 14. A major problem with such designs is the resulting gap 1404 in ballistic containment created by the area between the baffles 1400 in which the light fixture 1402 was placed. Additionally, such use of baffles 1400 creates unnecessary shadows as the light emitted from the light fixtures 1402 is partially obstructed by the lower portion of the baffle 1400. To alleviate such issues, embodiments of the present invention may include a flat, reinforced ceiling, which may serve to increase the floor to ceiling height relative to baffled ceiling designs, while maintaining a 360° area of ballistic containment for the live fire rounds. For example, as illustrated in FIG. 15, armored plating 1502 (such as AR500 ballistic steel, although other steel alloys and/or types of ballistic plating may be utilized) extends along a top of a roof structure of a container 1500 A lighting unit 1504 is mounted to the armored plating 1502 such that the lighting element 1504 extends below the armored plating 1502 and into the interior of the container 1500 and a cable 1506 extends through a small hole formed in the armored plating 1502. To protect the cable hole, a steel plate hood 1508 may be positioned about all or part of the cable hole in some embodiments. Oftentimes, the hood 1508 may be positioned downstream of an expected firing direction, although other placements are possible. To protect the lighting element 1504, an armored fin plate 1510 may be positioned on one or more sides of the lighting element 1504. While shown here as only being provided on an up range side of lighting element 1504, it will be appreciated that fin plates 1510 may be positioned on other or all lateral sides of the lighting element 1504. The fin plate(s) 1510 may extend downward from the armored plating 1502 and protect the lighting element 1504 from fired ballistic projectiles, while eliminating the gaps in ballistic protection that are present when baffles are utilized.

Oftentimes, an anti-ricochet material 1514, such as a rubber, polyboard, and/or other material (oftentimes between about 30 mm and 50 mm thick, with thicknesses between 35 mm and 45 mm being common, although other thicknesses may be utilized) may be affixed to the armored plating 1502. This may be done by affixing the anti-ricochet material 1514 to channels 1512 and/or other mounting structures that may be coupled with the armored plating 1502 and provide a gap between the armored plating 1502 and the anti-ricochet material 1514. In some embodiments, the fin plate 1510 may extend into the interior of the container 1500 such that a distal end of the fin plate 1510 is substantially flush with an inner surface of the anti-ricochet material 1514 to provide a seamless finish while maximizing the amount of protection for the lighting element 1504. Such arrangements also minimize the amount of obstruction of light emitted from lighting element 1504, thereby minimizing any shadows produced by the ballistic containment system.

While described generally as being constructed from standard ISO containers, it will be appreciated that some applications may involve the use of specially constructed containers, such may be manufacture to custom sizes, shapes (i.e., non-rectangular), tolerances, and/or other specifications to meet the needs of a particular application. Such embodiments, while increasing manufacturing costs, may provide more robust systems with greater flexibility in customizable options.

In some embodiments, the various containers described herein may come with pre-installed internal hardware to make assembly as simple as connecting the containers in the desired arrangement. For example, containers B1-B3 may include pre-installed shooting stalls, targets, target rails (for moving targets) and/or other hardware, while containers C1-C3 may include pre-installed bullet traps and/or targets, as well as ductwork for HVAC systems. Containers A1-A3 may include monitoring stations, computer and/or control equipment, and/or ductwork for HVAC connections. In other embodiments, the containers may merely provide a simple system of generating a ballistic containment perimeter, but equipment may need to be installed on-site. While more labor intensive, such embodiments may provide greater flexibility in customization options.

It will be appreciated that the various embodiments described herein may be utilized together to create optimum modular firing ranges to meet the needs of a particular application. For example, modular container systems such as described in relation to FIGS. 1 and/or 3 may be utilized with the HVAC container systems, sidewall pods, support structures, cleated connections, and/or light protection systems described herein in any combination to meet the particular needs of a firing range application. Moreover, while described with particular general arrangements (e.g., control area, firing range, bullet traps, etc.) it will be appreciated that any arrangement of containers and/or internal components is possible. The described embodiments are merely provided as examples and additional equipment may be added and/or described equipment may be omitted in accordance with the present invention to achieve the desired training environment.

FIG. 16 is a flowchart depicting a process 1600 for assembling a modular firing range according to embodiments. Process 1600 may be performed using any of the modular containers described herein. Process 1600 begins at block 1602 by selecting a plurality of modular containers from each of a first subset of modular containers, a second subset of modular containers, and a third subset of modular containers. The first subset of modular containers may include outer walls that define the first end of the modular firing range and side walls that define a first portion of a side of the modular firing range. For example, containers A1-A3 and/or D1 may fall into the first subset as either alone (D1) or in combination (A1 and A3, possibly in combination with A2) have walls on three sides that can form a closed first end of the modular firing range and at least a portion of the closed sides of the modular firing range. The second subset of modular containers may include outer walls that define the second end of the modular firing range and side walls that define a second portion of the side of the modular firing range. For example, containers C1-C3 and/or D3 may fall into the first subset as either alone (D3) or in combination (C1 and C3, possibly in combination with C2) have walls on three sides that can form a closed second end of the modular firing range and at least a portion of the closed sides of the modular firing range. The third subset may include modular containers that are coupleable between the first subset and the second subset to form a medial portion of the modular firing range. To do so, the third subset may include outer walls that define a third portion of the side of the modular firing range. For example, containers B1-B3 and/or D2 may fall into the first subset as either alone (D2) or in combination (B1 and B3, possibly in combination with B2) have walls on two opposing sides that can form at least a portion of the closed sides of the modular firing range. It will be appreciated that any number of containers of type B, containers D2, and/or containers A2, B2, C2 may be used in a particular firing range, as these containers may be added and/or subtracted to adjust the length and/or width of the modular firing range to meet the needs of a particular training application.

At block 1604, the selected plurality of modular containers are arranged to form a desired layout for the modular firing range. This may involve ensuring that a continuous outer wall is formed around at least a portion of the firing range that is to confine the live firing exercises. Depending on the containers chosen and the desired arrangement, the containers may be coupled in an end to end configuration and/or side by side configuration. Oftentimes, the modular firing range will be designed to include a control area in the first subset of modular containers, a plurality of firing lanes in the third subset of modular containers, at least one bullet trap in the second subset of modular containers, and/or a number of targets in the second and/or third subsets. However, it will be appreciated that numerous other arrangements are possible that include these and/or other features, as well as that may omit some of these features entirely or place some or all of the disclosed features in different subsets of modular containers. In some embodiments, some or all of the modular containers may be in staggered alignment with one another.

At block 1606, the selected plurality of modular containers are coupled together to form an armored outer perimeter that provides complete ballistic containment in all directions. In some embodiments, this may include fastening each of a plurality of angled cleats of each of the selected plurality of modular containers to a respective one of the plurality of angled cleats on an adjacent one of the selected plurality of modular containers. Such a process is described in greater detail with respect to FIG. 18. In some embodiments, a number of armored plates may be coupled to adjacent ones of the modular containers to cover joints formed between the adjacent ones of the modular containers. This may be done to ensure that a continuous ballistic containment area is maintained, even at connection points between the various containers. After the containers are coupled together, process 1600 may optionally include covering an interior surface of the armored perimeter with an anti-ricochet material, which may provide sound insulation to the firing range, as well as prevent dangerous ricochets of projectiles and to provide a more finished appearance.

It will be appreciated that process 1600 may also include the use of containers having support structures to enable open floor plan concepts as described herein. Additionally, process 1600 may include the use of sidewall pods, light protection systems, and/or the connection of HVAC systems as described elsewhere herein.

FIG. 17 is a flowchart depicting a process 1700 for assembling a modular firing range according to another embodiment of the invention. Process 1700 may be performed using any of the modular containers D1-D3 described herein. Process 1700 begins at block 1702 by selecting a first modular container, a second modular container, and plurality of additional modular containers. The first modular container is configured to form a first end of the modular firing range and includes two end walls and a first lateral sidewall. For example, the first container may be container D1 as container D1 includes walls on three sides that can form a closed first end of the modular firing range and at least a portion of the closed sides of the modular firing range. The second modular container is configured to form a second end of the modular firing range and includes two end walls and a second lateral sidewall. example, the first container may be container D3 as container D3 includes walls on three sides that can form a closed first end of the modular firing range and at least a portion of the closed sides of the modular firing range. The plurality of additional modular containers are coupleable between the first modular container and the second modular container to form a medial portion of the modular firing range. Each of the plurality of additional modular containers may include two end walls and no lateral sidewalls. For example, each additional container may be a container D2 as container D2 includes walls on two ends that can form at least a portion of the closed sides of the modular firing range.

At block 1704, the selected plurality of modular containers are arranged to form a desired layout for the modular firing range. This may involve ensuring that a continuous outer wall is formed around at least a portion of the firing range that is to confine the live firing exercises. The containers may be coupled in a side by side configuration. Oftentimes, the modular firing range will be designed to include a control area in the first modular container, a plurality of firing lanes in the additional modular containers, at least one bullet trap in the second modular container, and/or a number of targets in the second modular container and/or the additional plurality of modular containers. However, it will be appreciated that numerous other arrangements are possible that include these and/or other features, as well as that may omit some of these features entirely or place some or all of the disclosed features in different modular containers.

At block 1706, the selected plurality of modular containers are coupled together to form an armored outer perimeter that provides complete ballistic containment in all directions. In some embodiments, this may include fastening each of a plurality of angled cleats of each of the selected plurality of modular containers to a respective one of the plurality of angled cleats on an adjacent one of the selected plurality of modular containers. Such a process is described in greater detail with respect to FIG. 18. In some embodiments, a number of armored plates may be coupled to adjacent ones of the modular containers to cover joints formed between the adjacent ones of the modular containers. This may be done to ensure that a continuous ballistic containment area is maintained, even at connection points between the various containers. After the containers are coupled together, process 1700 may optionally include covering an interior surface of the armored perimeter with an anti-ricochet material, which may provide sound insulation to the firing range, as well as prevent dangerous ricochets of projectiles and to provide a more finished appearance.

It will be appreciated that process 1700 may also include the use of containers having support structures to enable open floor plan concepts as described herein. Additionally, process 1700 may include the use of sidewall pods, light protection systems, and/or the connection of HVAC systems as described elsewhere herein.

FIG. 18 is a flowchart depicting a process 1800 for assembling a modular firing range according to another embodiment of the invention. Process 1800 may be performed using any of the modular containers described herein. Process 1800 may begin at block 1802 by positioning a first modular container adjacent to a second modular container such that open interiors defined by each of the first modular container and the second modular container are joined to form at least a portion of the modular firing range and such that adjacent edges of the first modular container and the second modular container are in alignment with one another. The modular containers may be selected from any of the modular containers described herein (including sidewall pods and/or HVAC containers and/or storage containers) and may be positioned in any arrangement desired for a particular training application.

Once the modular containers are in the desired position, each of a first plurality of cleats of the first modular container may be coupled with a respective one of a second plurality of cleats of the second modular container at block 1804 to secure the first modular container and the second modular container together. For example, each of the first plurality of cleats may be aligned with the second plurality of cleats when the first modular container and the second modular container are in alignment with one another. Coupling each of the first plurality of cleats with the respective one of the second plurality of cleats may then involve securing each of the first plurality of cleats to the respective one of the second plurality of cleats using a fastener and/or clamping mechanism. For example, each cleat may be similar to cleats 1214 and/or 1302 described herein and may include a fixed portion that is mounted on a respective one of the plurality of modular containers and a securing portion that is configured to be removably secured to the securing portion of a corresponding one of the plurality of cleats. In some embodiments, the cleats have a generally L-shaped cross-section with one arm of the L being the fixed portion and the other arm of the L being the securing portion. The fixed portion of each of the plurality of cleats may be permanently or semi-permanently coupled with one of the plurality of modular containers, while the securing portion of each of the cleats is secured to the securing portion of a corresponding one of the cleats using one or more clamps and/or one or more fasteners that are inserted through the cleats. In some embodiments, the cleats may be spaced apart from each other by a distance of between about 1-10 feet along the edges of the containers. IN some embodiments, each of the plurality of cleats is between about 6 inches and 2 feet in length and the fixed portion and the securing portion form mating flanges or surfaces that are between about 1 inch and 6 inches in width.

In some embodiments, the process 1800 may optionally include positioning a third modular container adjacent to one or both of the first modular container or the second modular container such that an edge of the third modular container is adjacent one or both of the first modular container or the second modular container. The process 1800 may then involve coupling each of a third plurality of cleats of the third modular container with a respective one of a fourth plurality of cleats of one or both of the first modular container or the second modular container. It will be appreciated that any number of containers may be coupled together in such fashion.

In some embodiments, the users of the modular firing range may wish to disassemble the modular firing range. In such embodiments, process 1800 may include decoupling each of the first plurality of cleats from the respective one of the second plurality of cleats and separating the first modular container from the second modular container.

In some embodiments, each of the plurality of modular containers comprises an armored layer. Process 1800 may optionally include securing an armored plate to the armored walls of the first modular container and the second modular container such that the armored plate extends across and covers a joint formed between the armored walls of the first modular container and the second modular container.

FIG. 19 is a flowchart depicting a process 1900 for a creating modular firing range having an open floor plan. Process 1900 may be performed using any of the modular containers described herein and may include any arrangement of modular firing range needed for a particular application. Process 1900 may begin by removing at least one sidewall of a first modular container at block 1902. For example, the removed sidewall(s) may include an end wall and/or lateral sidewall of a modular container which has been cut or otherwise removed using mechanical, heat, laser, and/or other cutting techniques (or modular container may be initially formed without the one or sidewalls). In some embodiments, 1, 2, 3, 4 (or more if the container is non-rectangular) sidewalls may be removed from a single container, with some containers having only 0, 1, 2, or 3 sidewalls remaining. The at least one sidewall of the first modular container may be replaced with a first support structure at block 1904. The first support structure may include a first support beam coupled to a top edge of the first modular container and two or more columns supporting the first support beam. The connection between the first support beam and the two or more columns may be formed in any manner, such as those described in relation to FIG. 9A. At block 1906 at least one sidewall of a second modular container, which may be done in a similar manner as described above. At block 1908, the at least one sidewall of the second modular container may be replaced with a second support structure, which may include a second support beam coupled to a top edge of the second modular container and two or more columns supporting the second support beam.

At block 1910, the first modular container may be with the second modular container such that the two or more columns supporting the first support beam are substantially aligned with the two or more columns supporting the second support beam. This connection may be achieved using cleated connection techniques such as described elsewhere herein. In some embodiments, process 1900 further includes covering the aligned two or more columns of each of the first modular container and the second modular container with an anti-ricochet material. Some or all of the remaining exposed interior surfaces of the containers may also be covered with such a material.

In some embodiments, the support structures have generally U-shaped profiles, such as when only two columns are used in each support structure. In such cases, the columns may each be positioned in a corner of where the removed sidewall used to be located. In other embodiments, the support structures have generally M-shaped profiles. Such embodiments occur when a medial column is provided between two other columns.

FIG. 20 is a flowchart depicting a process 2000 for connecting an HVAC system with a modular firing range. Process 2000 may involve any of the modular container configurations described herein. Process 2000 may begin at block 2002 by coupling a first modular container that includes an HVAC supply unit with a first end of a modular firing range. The modular firing range be formed from at least one firing range modular container defining one or more firing lanes, such as a firing range constructed in accordance with the techniques described herein. The first modular container may define at least one air intake opening that is in fluid communication with the HVAC supply unit. The HVAC supply unit may include one or more HVAC units selected from an air conditioning unit, a heating unit, a humidifier, a dehumidifier, an air purification unit, and/or a refrigeration unit. Multiple of one or more of the same type of HVAC units may be used in a single container in some embodiments. In some embodiments, the one or more HVAC units are selected to simulate environmental conditions for a particular mission that is a subject of a particular training session as described in greater detail above with regards to FIG. 7.

Process 2000 may also include coupling a second modular container comprising an HVAC extraction unit with a second end of the modular firing range at block 2004. The second modular container may define at least one air vent opening that is in fluid communication with the HVAC extraction unit. In some embodiments, the HVAC extraction unit includes one or more fans that are configured to draw air out of the modular firing range. Both the first modular container and second modular container may be in vertical alignment with the modular firing range such that connections between the modular firing range and the HVAC containers may be made in a horizontal facing surface to enable improved weatherproofing of the HVAC connections. These connections may be done using ductwork in some embodiments.

FIG. 21 is a flowchart depicting a process 2100 of installing a modular sidewall enhancement onto a modular firing range according to one embodiment of the invention. Process 2100 may be done using any of the modular containers, firing ranges, and/or techniques described herein. Process 2100 may begin at block 2102 by assembling a main firing range body by coupling a plurality of modular containers to define a portion of an interior of the modular firing range in accordance with the disclosure herein. The interior of the modular firing range may define a plurality of firing lanes for live fire training exercises. At block 2104, at least one sidewall pod is coupled to at least one of the plurality of modular containers adjacent the plurality of firing lanes such that the at least one sidewall pod protrudes outward in a lateral direction from the plurality of firing lanes. The at least one sidewall pod is formed from at least one additional modular container. The at least sidewall pod includes one open side and walls on remaining sides such that the one open side is joined with the interior of the modular firing range. In some embodiments, the at least one sidewall pod overlaps and is coupled to two of the plurality of modular containers of the modular firing range. The connection between the sidewall pod and the modular containers may be done using the cleated connection techniques described herein. Additionally, process 2100 may include coupling at least one armored plate between the at least one sidewall pod an adjacent container of the plurality of modular containers of the modular firing range so as to cover a joint formed between the at least one sidewall pod and the adjacent container.

In some embodiments, the at least one sidewall pod has a depth that is less that a length of the plurality of firing lanes to provide close range live fire engagement training opportunities. In some embodiments, the at least one sidewall pod includes a first sidewall pod on a first side of the modular firing range and a second sidewall pod on a second side of the modular firing range. The outer periphery defined by outer walls of the modular firing range and the at least one sidewall pod forms an armored outer perimeter that provides complete ballistic containment in all directions.

At block 2106, at least one target and at least one bullet trap are installed in the at least one sidewall pod to provide lateral live fire engagement training opportunities.

FIG. 22 is a flowchart depicting a process 2200 for assembling a light protection system for a modular firing range. Process 2200 may be performed on any of the modular containers described herein, including storage containers, HVAC containers, sidewall pods, and the like. Process 2200 may begin at block 2202 by mounting a lighting element to armored plating that forms all or part of a ceiling structure of a modular firing range such that the lighting element is positioned within an interior of the modular firing range with a power cable of the lighting element extending through an aperture defined by the armored plating. In some embodiments, the armored plating includes AR500 steel and/or other steel alloy and may be between about 5 mm and 10 mm thick, although other thicknesses may be contemplated. For example, in embodiments in which the walls may be directly shot at, such as for sidewall pod embodiments, the thickness of the armored plating may be increased. At block 2204, a fin plate is affixed to the armored plating such that the fin plate extends downward from the armored plating and is positioned at least on a side of the lighting element that is proximate a live fire shooting location of the modular firing range. The fin plate may be configured to protect the lighting element from ballistic projectiles.

In some embodiments, process 2200 may optionally include affixing an anti-ricochet material to the armored plating. This may be done, for example, by using a number of channels that are coupled between the anti-ricochet material and the armored plating. An inner surface of the anti-ricochet material and a distal surface of the fin plate may be substantially flush with one another. In some embodiments, the anti-ricochet material comprises one or both of a rubber material or a polyboard material and may be between about 30 mm and 50 mm thick. Process 2200 may optionally include coupling a ballistic hood with the armored plating on an outer surface of the armored plating. The ballistic hood may be configured to protect the aperture from ballistic projectile

It will be appreciated that while described as separate processes, some or all processes 1600-2200 may be performed together (in whole or in part) to form a single modular firing range in accordance with the principles of the present disclosure. As just example, each container connection may be done using the cleated connection and/or open floor plan techniques described herein. Similarly, the use of light protection systems, HVAC systems, and sidewall pods may all be used in accordance with any of the processes described herein. Furthermore, while often described as being connected using cleated connections, it will be appreciated that in certain embodiments other container connection mechanisms may be utilized in addition to, or alternatively to, cleated connected as described herein. Additionally, some embodiments may use different mechanisms than described herein to enable open floor plans. Some embodiments may include features of one system described herein, while being combined with other solutions for creating modular firing ranges in accordance with the present invention.

The methods, systems, and devices discussed above are examples. Some embodiments were described as processes depicted as flow diagrams or block diagrams. Although each may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be rearranged. A process may have additional steps not included in the figure.

It should be noted that the systems and devices discussed above are intended merely to be examples. It must be stressed that various embodiments may omit, substitute, or add various procedures or components as appropriate. Also, features described with respect to certain embodiments may be combined in various other embodiments. Different aspects and elements of the embodiments may be combined in a similar manner. Also, it should be emphasized that technology evolves and, thus, many of the elements are examples and should not be interpreted to limit the scope of the invention.
